Question

DNA content has a tendency to double itself during section reproduction due to comping of the genetice material from two parents how can the problem of dna doubling be resolved to maintain the consistency of genetice material thogh out the species

Answer 1

the basic level of reproduction is making the copy of dna.when the both gametes contribute 23 pairs of chromosome to the progeny the resultant would doubled - 46 when this progeny mate with other the resultant would be doubled thud there would be no roof for other cells to prevent this situation during the time of reproduction the somatic cells contributes about half the no. of chromosome so that the upcoming progeny-of the dna level would be maintained
